Romans 16:17 - Now I urge you, brethren, keep your eye on those who cause dissensions and offenses contrary to the teaching which you learned, and turn away from them.

2 John 9-11 - Anyone who goes too far and does not abide in the teaching of Christ, does not have God; the one who abides in the teaching, he has both the Father and the Son. If anyone comes to you and does not bring this teaching,do not receive him in your house and do not give him a greeting: for the one who gives him a greeting participates in his evil deed.

The Bible is clear. Don't "participate in evil." Get your church out of the ELCA and if that doesn't happen, you should leave and find yourself a bible believing church.
